HVAC AC Installation Proposal Template
Win more AC installation jobs with a professional proposal template that includes tiered equipment options, transparent line items, and clear terms. Designed for residential HVAC contractors.
Why AC Installs Need Great Proposals
AC installations are the highest-ticket residential HVAC jobs most contractors handle. A full system replacement typically runs $5,000 to $12,000 depending on the region, equipment, and complexity. At that price point, homeowners are not making impulse decisions. They are collecting two or three bids, reading reviews, and comparing every line item.
Your proposal is where you win or lose the job. A detailed, professional document separates you from the contractor who texts a single number with no context. It answers the homeowner's core questions: What equipment are you recommending? Why that brand and size? What is included in the price? What happens after the install?
AC installs also have a seasonal urgency factor. When a system fails in July, the homeowner wants it replaced within days. A contractor who can deliver a polished proposal within hours of the site visit has a significant advantage over one who takes two days to follow up. Speed and professionalism together drive close rates above 50 percent.

Template Sections Breakdown
An effective AC installation proposal follows a specific structure. Each section serves a purpose in moving the homeowner from consideration to commitment.
Site Assessment Summary
Start by documenting what you found during the site visit. Note the existing system's make, model, age, and condition. If you took temperature readings, measured airflow, or identified ductwork issues, include those findings. This shows the homeowner you did a thorough evaluation and builds credibility for your equipment recommendation.
Load Calculation and Sizing
Reference your Manual J load calculation results. Specify the recommended tonnage and explain why. Many homeowners assume bigger is better, but an oversized unit short-cycles, wastes energy, and fails to dehumidify properly. Explaining the sizing rationale demonstrates expertise and justifies your equipment selection over a competitor who might recommend a different size.
Equipment Recommendation
Present the specific equipment you are recommending. Include the brand, model number, tonnage, SEER2 rating, and key features. If you are offering multiple tiers (and you should), clearly differentiate each option. Homeowners want to understand what the extra money buys them.
Installation Scope
Detail every step of the installation process. Include equipment removal, new equipment placement, refrigerant line connections, electrical work, thermostat installation, startup and commissioning, and cleanup. List anything that is excluded, such as electrical panel upgrades, ductwork modifications, or drywall repair, to prevent scope disputes.
Warranty and Maintenance
Separate your labor warranty from the manufacturer's parts warranty. Specify the duration and what each covers. If you offer a maintenance agreement that extends the warranty or provides priority service, mention it here as an add-on. This is also a natural place to link to your maintenance contract template.
Sample Line Items for AC Installation
Below is a detailed line item breakdown for a standard 3-ton split system AC installation. This example uses mid-range equipment pricing for a typical residential application.
| Item | Qty | Unit Price | Total |
|---|---|---|---|
| 3-Ton Condenser Unit (15.2 SEER2) | 1 | $2,850 | $2,850 |
| Matching Evaporator Coil (Cased, Upflow) | 1 | $825 | $825 |
| R-410A Refrigerant (Initial Charge) | 1 | $195 | $195 |
| Copper Line Set (3/8" x 3/4", 30 ft) | 1 | $340 | $340 |
| Wi-Fi Smart Thermostat | 1 | $185 | $185 |
| Disconnect Box and Whip | 1 | $95 | $95 |
| Concrete Equipment Pad (36" x 36") | 1 | $70 | $70 |
| Installation Labor (2 techs, 7 hrs) | 14 | $95/hr | $1,330 |
| Mechanical Permit and Inspection | 1 | $275 | $275 |
| Old Equipment Removal and Disposal | 1 | $175 | $175 |
| Total | $6,340 | ||
Pro Tip
Always itemize permits and disposal separately. Bundling them into a single "installation" line item makes your total look higher than competitors who exclude these costs. When itemized, homeowners can see these are pass-through expenses, not profit padding.
Equipment Options: Good, Better, Best
Offering three equipment tiers is one of the most effective ways to increase your average ticket. Industry data shows that 40 to 50 percent of homeowners select the middle tier when presented with three options. Without tiers, most choose the cheapest option or shop your price against competitors.
| Feature | Good | Better | Best |
|---|---|---|---|
| SEER2 Rating | 14.3 | 15.2 | 17.0+ |
| Compressor | Single-stage | Single-stage | Variable-speed |
| Sound Level | 72 dB | 68 dB | 56 dB |
| Thermostat | Basic programmable | Wi-Fi smart | Wi-Fi smart with zoning |
| Manufacturer Warranty | 5-year parts | 10-year parts | 10-year parts + compressor |
| Labor Warranty | 1 year | 2 years | 5 years |
| Est. Annual Energy Savings | Baseline | ~$120/year | ~$300/year |
| Installed Price (3-ton) | $5,200 | $6,340 | $9,450 |
Frame the tiers around the homeowner's priorities, not just the equipment specs. The "Good" option is the reliable workhorse that gets the job done. The "Better" option adds energy savings and comfort features that pay for themselves over time. The "Best" option is for homeowners who want the quietest, most efficient system available and plan to stay in the home for 10-plus years.

Tips for Presenting AC Proposals to Homeowners
How you present the proposal matters as much as what is in it. These techniques help you close more AC installation jobs.
- Present in person when possible. Contractors who walk homeowners through the proposal in person close at roughly double the rate of those who email and hope. If you cannot be there in person, schedule a video call to walk through the document together.
- Start with the problem, not the price. Review your site assessment findings first. Show the homeowner why their current system is failing or inefficient. The equipment recommendation should feel like the logical solution to a clearly defined problem.
- Recommend the middle tier first. Present your "Better" option as your recommendation, then show the "Good" option as a budget alternative and the "Best" option as a premium upgrade. Anchoring on the middle option makes it feel like the balanced, sensible choice.
- Show the monthly payment. A $6,340 lump sum is intimidating. A $105/month financed payment is manageable. If you offer financing, always show both numbers. Many contractors report that including a financing option increases close rates by 15 to 25 percent.
- Address energy savings in dollars. A 15.2 SEER2 system replacing a 10 SEER unit can save $300 to $500 per year on cooling costs depending on climate zone and usage. Translate efficiency ratings into money saved because homeowners do not intuitively understand SEER values.
- Set a follow-up timeline. Tell the homeowner you will follow up in 48 hours. This sets expectations and gives them time to review without feeling pressured. Most residential AC jobs close within 3 to 5 days of the proposal being delivered.
Pro Tip
Include a photo of the new equipment in the proposal. Homeowners are visual buyers. A product image of a clean, modern condenser unit next to a photo of their aging, rust-stained system makes the upgrade tangible and desirable.
